Specification of Letters Patent.

Patented Dec. 28, 1915.

Application filed. August 11, 1915. Serial No. 44,893.

To all whom it may concern.

Be it known that I, WILLIAM S. TRownames, a citizen of the UnitedStates, re-

siding at Chicago, in thecounty of Cookand'State of Illinois, haveinvented certain new and useful Improvements in Striking- Blocks, ofwhich the following is a specificars.

Ti l

'mum resistance to distortion.

It is common practice to provide deadwood or a striking block on the endsills of cars in order to absorbexcessive bufling shocks, this blockbeing located to lie behind a portion of the car coupler. Blocks of castmaterial are commonly employed butit is welllmown that castings aresubject to breakage under shocks more quickly than rolled or wroughtmetal. I have, therefore, designed a striking block adapted to be formedfrom rolled or forged metal and so constructed as to provide the maxi-Such a device inay be cheaply constructed from plates -readily availableon the market and is adapted for application to cars having either Woodor metal end sills.

Other objects Will beapparent from the drawings wherein Figure 1 is atop view of the preferred embodiment of my invention; Fig. 2 is a sideelevation; and Fig. 3 is a sectional view on line 3-3 of Fig. 2.

Referring to the drawings, 10 is the upstanding leg of the angleattaching portion, and 11 the bottom leg. The block is at tached to theend sills of cars in the position shown inFig. 2, the portion 10 beingprovided with bolt holes 12, and the bottom 11 with bolt holes 13through which bolts (not shown) secure the block to the sills (notshown). a

. In shearing and shaping the plate I provide a centrally disposedtongue which I bend into the shape shown in Fig. 3. The tongue has anupright face 14, a rearwardly inclined top 15 and a vertical end flange16 which is riveted or otherwise secured to the leg 10. To increase thestrength and rigidity of the stop I prefer to 'form corrugations or ribs17 in the top 15 thereby providing a stop of great strength though muchlighter than a cast block of the same resistance. The face 14: receivesthe blows from the coupler head and therefore must be stronglyreinforced. To form an abutment for the flange 16 I prefer to turn downa lip 18 in leg 10. This lip will prevent any vertical movement of theflange 16 when blows are struck on the face 14k thereby preventingshearing of the rivets 19 if such are used.

It is obvious that some modifications may be made and I suchmodifications as come within the scope of my claims I consider as withinthe spirit of my invention.

I claim:

1. In a striking block, the combination with integral vertical andhorizontal attaching plates, of a tongue member integral with saidhorizontal plate, said tongue being bent upwardly and rearvvardly andprovided with a flanged end, said rearwardly extending portion beingprovided with ribs, said flange lying against said vertical portion, andfastening means to secure said portions together, substantially asdescribed.

2-. In a striking block, the combination with integral vertically andhorizontally disposed attaching plates, of a stop member integral withsaid horizontally disposed plate, said stop member bent upwardly andrearwardly and provided with a flanged end, said rearwardly extendingportion provided with ribs, said vertical attaching plate memberprovided with a forwardly projecting lip, the flanged end of said stopadapted to bear against said vertical plate member and abut against saidlip, and means for securing said flanged end to said vertical platemember, substantially as described.
